Here's how much actual pumpkin is in that pumpkin spice latte

For some, the changing leaves are indicative of fall, while for
others it's that alluring scent of the wildly popular
pumpkin-spice latte (PSL) — a seasonal coffee drink that
mysteriously gives you a burst of delicious pumpkin pie
flavor without the hassle of baking or dish-washing.

Surprisingly, those iconic spices that go into a home-made
pumpkin pie constitute less than 11% of what
gives your fall beverage its incredible flavor. And an
even smaller amount of actual pumpkin is in there.

So how does the PSL manage to taste like pumpkin
pie when it has so little of makes pumpkin pie so
awesome? For the answer, we must turn to science.
